Guide dogs help blind people who cannot get around by themselves．Although Yorkshire terriers and poodles are good companion dogs，guide dogs are chosen from lager breeds(品种)such as German shepherds，golden retrievers，and Labrador retrievers．The young dogs are raised by families until they are eighteen months old．During this time，they get lots of love and attention，but they are also taught to obey．Then the dogs go to a special school where，for four months，they work with a sighted trainer，an individual who can see．The dog forms a close relationship with this person who teaches it how to follow directions such as right，left，straight ahead，and stop．The young dog also learns to watch out for dangerous traffic and wait until it is safe to cross a busy street.
When the dog is two years old，it starts training with the blind person it will live with. The dog and its new owner make many trips from downtown to where the blind person lives so the dog becomes familiar with the normal atmosphere．During the training，a sighted trainer always remains with them. A blind person who is getting a guide dog for the first time will train for about a month. If the individual has had a dog before，the training takes about three weeks．After the training，the blind person depends on the guide dog for between seven and twelve years．At that point，the working dog become a family pet and the owner needs to train with a younger guide dog．
